Struct PmiState 

pub struct PmiState {
    pub views: Vec<PmiView>,
    pub id_counter: u64,
}

The document’s pmi block. Loading it folds every view’s legacy display.hidden list into that view’s baseline hide step (see PmiDisplay), so every reader — the run, the parts library, STEP export, plugins, the 3D PDF — sees one representation.

Fields

views: Vec<PmiView>

id_counter: u64

Mints every view AND annotation id (VIEW{n}, DIM{n}, …); monotonic, never reused, re-seeded from the largest numeric suffix on load.

Implementations

impl PmiState

pub fn set_view_baseline(&mut self, view_id: &str, names: &[String]) -> bool

Replace view view_id’s baseline hide step with one naming names (none when empty), keeping the old step’s id and place. False when nothing changed or there is no such view.

pub fn hide_in_view( &mut self, view_id: &str, names: &[String], ) -> Option<String>

Hide names in view view_id as a new hide step (the viewport’s hide while the view is active): only the names the view does not hide yet. The new step’s id, or None when nothing new is hidden.

pub fn show_in_view( &mut self, view_id: &str, names: &[String], solids: &[String], ) -> bool

Show names in view view_id (the viewport’s show while the view is active): every enabled hide step drops them; a step target naming a whole component one of them belongs to becomes that component’s other solids (from solids, the scene’s names); a step left with no target goes. True when a step changed.

pub fn set_view_hidden( &mut self, view_id: &str, names: &[String], solids: &[String], ) -> bool

Make view view_id hide exactly names among solids (MCP pmi_set_view_display’s hidden): what it hides beyond them is shown (Self::show_in_view), and what it does not hide yet joins its baseline step. True when a step changed.

pub fn next_id(&mut self, prefix: &str) -> String

Mint the next id with prefix (VIEW → VIEW3). The counter is re-seeded first from the largest numeric suffix already in the block, so an edited or merged document never hands out a colliding id.

pub fn find_view(&self, id: &str) -> Option<&PmiView>

pub fn find_view_mut(&mut self, id: &str) -> Option<&mut PmiView>

pub fn find_annotation(&self, id: &str) -> Option<(&PmiView, &PmiAnnotation)>

The annotation with id and its owning view.

pub fn locate_annotation(&self, id: &str) -> Option<(usize, usize)>

The owning view id and index of annotation id.

pub fn find_annotation_mut(&mut self, id: &str) -> Option<&mut PmiAnnotation>

pub fn datum_letters(&self) -> Vec<(String, String)>

Every datum letter defined in the part (any view), in definition order, with the defining annotation’s id — the part-level datum registry a feature control frame validates its references against.

pub fn next_datum_letter(&self) -> Option<String>

The next unused datum letter: A–Z skipping I, O and Q (ASME Y14.5), then AA, AB, … (None only past ZZ).

pub fn is_empty(&self) -> bool

Whether the block carries anything worth persisting.
